A novel catheter-mounted echocardiographic probe successfully provided continuous left ventricular cavity measurements and clear definition of motion patterns of the mitral valve and ventricular walls.
Does a catheter-mounted echocardiographic probe allow for continuous monitoring of left ventricular size and motion in humans?
A novel catheter-mounted echocardiographic probe demonstrates feasibility for continuous intracardiac monitoring of left ventricular size and motion.
Because no accurate and readily applied method exists for continuous recording of left ventricular cavity dimensions and wall motion in man, we designed a catheter-mounted echocardiographic probe. The purpose of this report is to describe the instrumentation, technique, limitations, complications and preliminary observations employing the probe in humans. The echo transducer built into a cardiac allowed positioning in the right heart under fluoroscopy. The echo signals permitted continuous left ventricular cavity measurements at rest and during maneuvers. Our results suggest that intracardiac echo may be able to provide clear definition of motion patterns of the mitral valve and left ventricular walls. The ultrasonic catheter is an instrument that potentially offers a new technique for continuous monitoring of left ventricular size and motion.
Conetta et al. (1979) studied Left ventricular monitoring. Catheter-mounted echocardiographic probe (intracardiac M-mode echocardiography) was evaluated on Continuous left ventricular cavity measurements and motion patterns. A novel catheter-mounted echocardiographic probe successfully provided continuous left ventricular cavity measurements and clear definition of motion patterns of the mitral valve and ventricular walls.
